LUCK.

Application filed December 6, 1921. Serial No. 520,229.

struction and arrangement oi? the parts and i iomhination of parts hereinafter more fully set :iorth in the following specification and pointed out in detail in the claim:

in the accompanying drawing- Figure l is a top plan view showing the temporary locking device in the unlocked position. 1

Figure 2 is a similar-view to Figure 1 but showing the temporary locking device in the locked position.

Figure 3 is a side elevation of l ig'ure 1.

Figure 4i is an inverted plan view with the hack of the case removed andshowing the parts in the unlocked position.

Figure 5 is a detail plan view of the tempera v locking device.

Re erring to the accompanying drawings, forming part of this specification, and

in which like reference numerals designate.

like parts throughout the several. views thereof. 1 designates the case having a hasp 2 adapted to be secured in any ed. position so that the lock can be brought down over the eye or staple 3. The said staple 3 is secured in position by screws and projects through the central opening l of the lock. Uri the upper surface of the;

lock case is a temporary locking device 5 having two points 6 adapted to be turned to project through the eye or staple 3, as shown in Figure 2, in which position the end? of the temporary locking device covers the keyhole 8. The said temporary lockingdevice 5 is revoluble under the lugs 9 on the upper surface of the case 1. Within the case 1 is a locking bolt 10 on the end of the lever 11. which latter is pivoted at 12 and is operated by the bar 18 pivoted to the.

lever 11 at let. The key 15 operates against the tumblers 16 and bar 13 to throw the lever 11 and the locking bar 10. Within the is a metal spring 17 secured at one end to tiltcase 1 and having a push button 18 on its free end. When said spring 17 is pushed in against the tumblers l6 and bar the locking bar 10 will be thrown from the unlocked to the locked position, thus dispensing with the use of the key to lock the device.

The staple 3 is first secured in position, and the hasp 2 is then secured in positionso that the look can be brought down over the staple, with the latter projecting through the central opening at, in which position the locking bar 10 ismoved, by key or by the push button 18, to the locked position.

i-iaving thus described my invention, what I claim is:

A look comprising a casing having an opening therethrough, staple adapted to pro ect through said opening a locking bar pivoted Wl'tlllll. said casing and adapted to project through said staple, a key-bar pivoted to said locking ban, and a key adapted to co-operate with said locking bar. I

In testimony whereof I afiix my Signature.
